Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5104338-9

The TE Connectivity 5104338-9 is the direct active equivalent of the obsolete 104338-9. This part maintains identical electrical and mechanical specifications, including 50 positions, 2.54mm pitch, through-hole solder termination, and push-pull fastening. The 5104338-9 carries active product status and RoHS compliance, making it the preferred choice for new designs and obsolescence replacement. Packaging is available in tube format.

Secondary Recommendations: HARTING SEK Series

HARTING 09185506324, 09185506322, 09185505324, 09185507324, and 09195506324 provide functional equivalence with 50-position, 2.54mm pitch headers, shrouded 4-wall construction, and through-hole solder termination. These parts feature ROHS3 compliance and active product status. Operating temperature range extends to -55°C ~ 125°C. Fastening type is latch holder rather than push-pull. Contact post lengths vary between 0.114" (2.90mm) and 0.177" (4.50mm), requiring PCB footprint verification. Insulation material differs from the main part, utilizing polybutylene terephthalate (PBT) or polycyclohexylenedimethylene terephthalate (PCT) glass-filled compounds.

Tertiary Recommendations: 3M 303 Series and Amphenol ICC Quickie™ Series

3M 30350-6002HB and Amphenol ICC 75869-108LF, 75869-308LF, and 87610-250LF provide functional equivalence with 50-position, 2.54mm pitch headers and push-pull fastening. These parts maintain shrouded 4-wall construction and through-hole solder termination. All carry RoHS compliance and active product status. Contact post lengths and insulation heights vary slightly from the main part. Amphenol ICC parts feature GXT™ gold mating contact finish with enhanced durability characteristics.

Compliance Considerations

The obsolete 104338-9 is RoHS non-compliant. All recommended substitutes carry RoHS compliance (RoHS Compliant or ROHS3 Compliant), supporting regulatory requirements for new designs and manufacturing environments subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5104338-9 directly replace the obsolete 104338-9 in existing designs?

A: Yes. The 5104338-9 maintains identical electrical and mechanical specifications, including 50 positions, 2.54mm pitch, through-hole solder termination, push-pull fastening, and operating temperature range of -65°C ~ 105°C. PCB footprints and mating interface compatibility are preserved. The primary difference is RoHS compliance status and active product availability.

Q: What is the difference between push-pull and latch holder fastening types?

A: Push-pull fastening uses a sliding mechanism for connector engagement and disengagement. Latch holder fastening employs a latching mechanism for secure connection. These fastening types are not interchangeable; connector selection must match the mating receptacle design. HARTING SEK series parts use latch holder fastening, while TE Connectivity 5104338-9, 3M 30350-6002HB, and Amphenol ICC Quickie™ series use push-pull fastening.

Q: Are contact post length variations significant for PCB compatibility?

A: Yes. Contact post length determines solder joint depth and PCB hole engagement. The main part specifies 0.120" (3.05mm) post length. HARTING parts range from 0.114" (2.90mm) to 0.177" (4.50mm), and 3M parts specify 0.110" (2.79mm). Shorter post lengths may result in insufficient solder joint formation; longer post lengths may cause PCB damage during insertion. PCB design must accommodate the selected part's post length specification.

Q: What is the significance of contact material differences?

A: The main part uses phosphor bronze contacts; substitutes employ brass or copper alloy materials. These materials provide equivalent electrical conductivity and mechanical durability for 1A per contact current ratings. Contact material selection affects spring characteristics and wear resistance. All specified materials support the connector's functional requirements.

Q: Do insulation material differences affect connector performance?

A: Insulation materials differ across substitutes: the main part uses unspecified material; TE Connectivity 5104338-9 uses polyphthalamide (PPA) glass-filled; HARTING parts use polybutylene terephthalate (PBT) or polycyclohexylenedimethylene terephthalate (PCT) glass-filled; 3M and Amphenol ICC parts use thermoplastic or polyester glass-filled compounds. All materials carry UL94 V-0 flammability rating and support the specified operating temperature ranges. Material selection affects mechanical rigidity and environmental resistance but does not alter electrical performance for this application.

Q: What packaging options are available for substitute parts?

A: TE Connectivity 5104338-9 is available in tube packaging. HARTING parts are available in bulk or tray packaging. 3M 30350-6002HB is available in tray packaging. Amphenol ICC Quickie™ series parts are available in tube packaging. Packaging selection affects inventory management and component handling but does not influence electrical or mechanical compatibility.

Q: Is the operating temperature range difference between -65°C ~ 105°C and -55°C ~ 125°C significant?

A: Operating temperature range differences reflect material and design variations. The main part and TE Connectivity 5104338-9 specify -65°C ~ 105°C. HARTING parts specify -55°C ~ 125°C, providing extended high-temperature capability but reduced low-temperature performance. Application requirements determine acceptable temperature range. Amphenol ICC parts do not specify operating temperature. Design specifications must confirm compatibility with the selected substitute's temperature rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitutes carry RoHS compliance (RoHS Compliant or ROHS3 Compliant). The obsolete main part is RoHS non-compliant. RoHS compliance is mandatory for designs subject to European Union Restriction of Hazardous Substances directives and similar regulatory frameworks.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The main part specifies 15.0µin (0.38µm) mating finish and 100.0µin (2.54µm) post finish. Amphenol ICC 75869-108LF specifies 30.0µin (0.76µm) mating finish, providing enhanced durability. Thicker finishes reduce contact wear during mating cycles. All specified finishes support the connector's functional requirements and current ratings.
