Engineering Selection Recommendations

For Direct Replacement (Highest Compatibility):

The part 5104338-4 is the primary direct equivalent to the obsolete 104338-4. Both parts maintain identical connector architecture, pitch spacing, position count, and mounting configuration. The 5104338-4 is active with higher inventory availability (1420 units) and achieves RoHS compliance status. Material composition differences (Brass contact material and Tin post finish versus Phosphor Bronze and Tin-Lead) do not compromise electrical performance within the specified 1A per contact current rating. The insulation material upgrade to Polyphthalamide with glass fill provides enhanced mechanical properties. This part is suitable for direct substitution in new designs and legacy system updates.

For Amphenol ICC Quickie™ Series (Push-Pull Fastening Compatibility):

Parts 10056844-120LF, 75869-104LF, 75869-204LF, and 75869-304LF maintain push-pull fastening compatibility with the main part, eliminating connector interface redesign requirements. These parts are active with RoHS compliance and substantial inventory levels. The 75869-104LF and 75869-304LF variants employ Phosphor Bronze contact material matching the original specification. Contact length post variations (0.079" to 0.120") require PCB layout verification for through-hole mounting depth compatibility. The 75869-204LF variant features Tin mating finish and is available in the highest inventory quantity (4561 units), offering supply chain advantages for high-volume applications.

For HARTING SEK Series (Latch Fastening Compatibility):

Parts 09185207914, 09195205324, 09195206324, and 09195207324 provide functional substitution with latch-based fastening mechanisms. These parts are active with ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). The HARTING parts employ Copper Alloy contact material with Tin post finish and are available in moderate inventory quantities (838 to 1162 units). Connector interface redesign is required to accommodate latch holder or latch lock/eject hooks fastening. The 09185207914 variant includes mounting flange features and extended insulation height (0.681"), suitable for applications requiring mechanical stabilization.

For Right-Angle Mounting (Orientation Change):

Part 09185206321 provides right-angle mounting orientation with identical pitch and position specifications. This variant requires PCB layout modification and is suitable only for applications where vertical-to-right-angle orientation change is acceptable. The part is active with ROHS3 compliance and moderate inventory availability (1162 units).

Compliance Considerations:

All substitute parts achieve RoHS compliance (RoHS Compliant or ROHS3 Compliant status), addressing regulatory requirements that the obsolete 104338-4 does not meet. REACH status varies: TE Connectivity 5104338-4 is REACH Unaffected; HARTING parts are REACH Unaffected; Amphenol ICC parts 75869-104LF, 75869-204LF, and 75869-304LF are REACH Affected. Applications subject to REACH restrictions should prioritize REACH Unaffected alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 5104338-4 be used as a direct replacement for the 104338-4 in existing designs?

A: Yes. The 5104338-4 maintains identical electrical and mechanical specifications including 20 positions, 2.54mm pitch, through-hole mounting, shrouded 4-wall construction, and push-pull fastening. Material composition differences (Brass vs. Phosphor Bronze contact material; Tin vs. Tin-Lead post finish) do not affect performance within the 1A per contact current rating. The 5104338-4 is active and RoHS compliant, making it the preferred direct equivalent.

Q: What are the key differences between push-pull fastening (104338-4, 5104338-4, Amphenol ICC parts) and latch fastening (HARTING parts)?

A: Push-pull fastening uses a sliding mechanism for connector engagement and disengagement, while latch fastening employs mechanical hooks or holders. These fastening types are not interchangeable without connector interface redesign. The mating connector must be compatible with the fastening mechanism. Push-pull fastening is suitable for applications requiring frequent mating cycles; latch fastening provides positive mechanical retention.

Q: Are the Amphenol ICC Quickie™ series parts (75869-104LF, 75869-204LF, 75869-304LF) interchangeable with each other?

A: These parts share identical connector architecture, pitch, position count, and fastening type but differ in contact finish composition. The 75869-104LF and 75869-304LF feature Gold mating finish with different thickness specifications (30.0µin vs. 15.0µin); the 75869-204LF features Tin mating finish. Selection depends on application requirements for contact finish durability and corrosion resistance. All three parts are electrically compatible and suitable for the same through-hole PCB mounting applications.

Q: What is the significance of contact length post variations across substitute parts?

A: Contact length post determines the depth of solder joint penetration into the PCB. The main part 104338-4 specifies 0.120" (3.05mm) post length. Substitute parts range from 0.079" (2.00mm) to 0.177" (4.50mm). Shorter post lengths (10056844-120LF at 0.079") require PCB through-hole depth adjustment to ensure adequate solder joint formation. Longer post lengths (09185206321 at 0.177") may require PCB thickness verification. PCB design must accommodate the selected part's post length specification.

Q: Which substitute parts are suitable for applications with REACH compliance requirements?

A: REACH Unaffected parts include TE Connectivity 5104338-4 and all HARTING SEK series parts (09185206321, 09185207914, 09195205324, 09195206324, 09195207324). Amphenol ICC Quickie™ series parts (75869-104LF, 75869-204LF, 75869-304LF) are REACH Affected. Applications subject to REACH restrictions should prioritize REACH Unaffected alternatives.

Q: What is the operating temperature range difference between the main part and HARTING substitutes?

A: The main part 104338-4 operates from -65°C to 105°C. HARTING SEK series parts operate from -55°C to 125°C, providing extended high-temperature capability. Amphenol ICC Quickie™ series parts do not specify operating temperature range. Applications requiring operation below -55°C must use the main part or TE Connectivity 5104338-4 equivalent.

Q: How do insulation material differences affect connector performance?

A: The main part 104338-4 does not specify insulation material. The 5104338-4 uses Polyphthalamide (PPA) with glass fill; HARTING parts use Polybutylene Terephthalate (PBT) or Polycyclohexylenedimethylene Terephthalate (PCT) with glass fill; Amphenol ICC parts use Thermoplastic or Thermoplastic with glass fill. All materials achieve UL94 V-0 flammability rating. Glass-filled materials provide enhanced mechanical strength and dimensional stability. Material selection does not affect electrical performance but influences mechanical durability and environmental resistance.

Q: Is the right-angle mounting variant (09185206321) suitable for vertical mounting applications?

A: No. The 09185206321 is specifically designed for right-angle mounting orientation, where the connector body extends perpendicular to the PCB surface. This part is not suitable for vertical mounting applications requiring the connector body to extend parallel to the PCB surface. Vertical mounting applications must use parts specified for vertical orientation (104338-4, 5104338-4, 09185207914, 09195205324, 09195206324, 09195207324, 10056844-120LF, 75869-104LF, 75869-204LF, 75869-304LF).

Q: What packaging options are available for substitute parts?

A: Packaging varies across substitutes: 5104338-4 is supplied in Tube packaging; HARTING parts are supplied in Bulk or Tray packaging; Amphenol ICC parts are supplied in Tube packaging. Packaging selection affects handling, storage, and automated assembly compatibility. Tube packaging is suitable for automated pick-and-place equipment; Bulk and Tray packaging are suitable for manual assembly or tape-and-reel conversion.
