Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 103735-6 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (7)
• Pitch spacing (0.100" / 2.54mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact finish on mating surface (Gold)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact length specifications (Mating: 0.230", Post: 0.130", Overall: 0.545")
• Insulation height (0.535")
• Contact shape (Square)

Material & Certification Parameters:

• Insulation material (Thermoplastic)
• Flammability rating (UL94 V-0)
• Series designation (AMPMODU MTE)

The substitute part 5-103735-6 maintains full equivalence across all electrical and mechanical parameters. Variations in post-contact finish material (Tin-Lead versus Tin) and regulatory compliance status (RoHS and REACH) do not affect functional interchangeability in the connector interface itself.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TE Connectivity 103735-6 and 5-103735-6 are electrically and mechanically interchangeable for all connector interface functions. Selection between these parts is determined by regulatory and compliance requirements rather than functional performance.

RoHS Compliance Consideration:

The 103735-6 is RoHS non-compliant, while the 5-103735-6 is RoHS Compliant. Applications subject to RoHS Directive 2011/65/EU or equivalent regional regulations require the 5-103735-6 variant. The primary difference enabling RoHS compliance in the 5-103735-6 is the post-contact finish specification (Tin instead of Tin-Lead), which eliminates lead content from the solder termination material.

REACH Compliance Consideration:

The 103735-6 carries REACH Affected status, indicating the part contains substances of concern under REACH Regulation (EC) 1907/2006. The 5-103735-6 lists REACH status as Vendor Undefined. Applications requiring confirmed REACH compliance documentation should reference the substitute part with clarification from the vendor.

Inventory and Availability:

The 5-103735-6 maintains higher inventory levels (2968 Pcs) compared to the 103735-6 (829 Pcs), supporting supply chain continuity for high-volume production requirements.

Post-Contact Finish Equivalence:

The transition from Tin-Lead to Tin post-contact finish does not compromise solder joint reliability or mechanical performance. Both finishes meet the same solderability and thermal cycling requirements for through-hole termination applications.

Frequently Asked Questions (FAQ)

Q: Are the 103735-6 and 5-103735-6 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shrouding configuration, contact geometry, mounting dimensions, and through-hole termination interface. They are direct mechanical substitutes.

Q: What is the functional difference between Tin-Lead and Tin post-contact finishes?

A: Both finishes provide equivalent solder joint performance and thermal cycling reliability for through-hole applications. The Tin finish in the 5-103735-6 eliminates lead content, enabling RoHS compliance. No functional performance difference exists between the two finishes in standard soldering processes.

Q: Which part should be selected for RoHS-regulated applications?

A: The 5-103735-6 is RoHS Compliant and must be used for applications subject to RoHS Directive 2011/65/EU or equivalent regional regulations. The 103735-6 is RoHS non-compliant and is not suitable for RoHS-regulated markets.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both connectors carry identical electrical specifications: 3A current rating, 0.100" (2.54mm) pitch, 7-position configuration, and -65°C ~ 105°C operating temperature range. Electrical performance is equivalent.

Q: Can the 103735-6 be used in medical device applications?

A: Both the 103735-6 and 5-103735-6 list medical applications in their specification. However, medical device applications often require RoHS compliance as part of regulatory approval. The 5-103735-6 is the appropriate selection for medical devices subject to RoHS requirements.

Q: What is the significance of the keying slot feature?

A: The keying slot provides mechanical polarization, preventing incorrect mating orientation between the header and its corresponding connector. This feature is identical on both the 103735-6 and 5-103735-6.

Q: Is the packaging identical for both parts?

A: Yes. Both connectors are supplied in tube packaging. Inventory quantities differ (829 Pcs for 103735-6 and 2968 Pcs for 5-103735-6), but the packaging format is identical.

Q: What does "Shrouded - 4 Wall" mean?

A: This designation indicates the connector header includes four walls of insulation material surrounding the contact array, providing mechanical protection and preventing accidental contact with the male pins during handling and assembly.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the 103735-6 and 5-103735-6 are specified for automotive applications. The 5-103735-6 is the preferred selection for automotive applications in regions requiring RoHS compliance.

Q: What is the difference between "Contact Length - Mating" and "Contact Length - Post"?

A: Contact Length - Mating (0.230") specifies the length of the contact that engages with the mating connector. Contact Length - Post (0.130") specifies the length of the contact that extends through the printed circuit board for solder termination. Both dimensions are identical on both parts.
