Engineering Selection Recommendations

Primary Equivalent (Direct Substitution): The 61300621121 (Würth Elektronik WR-PHD series) and 826942-3 (TE Connectivity AMPMODU Mod II) are the closest functional equivalents to the 77313-102-06LF. Both maintain the core 6-position, 2-row, 0.100" pitch configuration with through-hole solder termination and push-pull fastening. The 61300621121 offers ROHS3 compliance and operates across -40°C to 105°C, while the 826942-3 extends the lower temperature limit to -65°C and supports 5A current rating. Both are active-status products with full inventory availability.

Sullins Connector Solutions Variants (Post-Length Dependent): The Sullins PBC03 and PEC03 series provide multiple contact post-length options to accommodate varying board-to-board spacing requirements. Selection between these variants depends on the specific application's PCB thickness and connector stack-up geometry:

PBC03DAAN and PEC03DAAN: 0.120" (3.05mm) post length for standard 1.6mm PCB applications
PBC03DABN and PEC03DABN: 0.230" (5.84mm) post length for extended spacing
PBC03DACN and PEC03DACN: 0.320" (8.13mm) post length for greater separation
PBC03DADN: 0.420" (10.67mm) post length for maximum spacing
PEC03DAHN: 0.820" (20.83mm) post length for specialized applications

All Sullins variants feature ROHS3 compliance, UL94 V-0 flammability rating, and -65°C to 125°C operating temperature range. The PBC03 series uses gold-plated mating contacts, while the PEC03 series uses tin-plated mating contacts. Both series employ phosphor bronze contact material and polybutylene terephthalate insulation.

Compliance Considerations: All substitute parts maintain UL94 V-0 flammability compliance and RoHS or ROHS3 compliance status. The 77313-102-06LF carries RoHS Compliant status, while Würth and Sullins variants carry ROHS3 Compliant status. TE Connectivity 826942-3 maintains RoHS Compliant status. All parts are active-status products with confirmed inventory availability.

Temperature Range Limitations: The 77313-102-06LF operates to 130°C maximum. The 61300621121 (Würth) is limited to 105°C maximum and is not suitable for applications requiring the full 130°C upper temperature range. The 826942-3 (TE) and all Sullins variants operate to 105°C or 125°C maximum and should be evaluated against specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the 61300621121 (Würth) be used as a direct replacement for the 77313-102-06LF?

A: The 61300621121 is functionally compatible for most applications due to matching pitch, position count, row configuration, and contact geometry. However, the Würth part operates only to 105°C maximum temperature, compared to 130°C for the Amphenol part. Applications requiring operation above 105°C must use the 77313-102-06LF or select alternatives with higher temperature ratings such as the Sullins PBC03 or PEC03 series (125°C maximum).

Q: What is the difference between PBC03 and PEC03 Sullins variants?

A: The primary difference is contact finish on the mating surface. PBC03 series connectors feature gold-plated mating contacts, while PEC03 series connectors feature tin-plated mating contacts. Both series use tin-plated posts and phosphor bronze contact material. Selection depends on application requirements for contact finish and mating surface characteristics. Both series maintain identical pitch, position count, row spacing, and electrical ratings.

Q: How do I select the correct Sullins post-length variant?

A: Post length selection is determined by the required board-to-board spacing in your application. The contact post length extends from the insulation body into the PCB. Standard 1.6mm PCB applications typically use the 0.120" (3.05mm) post-length variants (PBC03DAAN or PEC03DAAN). Thicker PCBs or applications requiring greater connector separation use longer post-length variants. Measure the required spacing from the top of one PCB to the bottom of the mating connector to determine the appropriate post length.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 77313-102-06LF carries RoHS Compliant status. The 61300621121 (Würth) and all Sullins variants carry ROHS3 Compliant status. The 826942-3 (TE) carries RoHS Compliant status. All parts meet RoHS or ROHS3 requirements and are suitable for applications with RoHS compliance mandates.

Q: What is the current rating difference between the 77313-102-06LF and 826942-3?

A: The 77313-102-06LF is rated for 3A per contact. The 826942-3 (TE Connectivity) is rated for 5A per contact. For applications requiring higher current capacity, the 826942-3 provides additional current-handling capability. However, the 826942-3 operates to 105°C maximum, compared to 130°C for the Amphenol part.

Q: Can I use the 826942-3 in high-temperature applications?

A: The 826942-3 operates across -65°C to 105°C. Applications requiring operation above 105°C cannot use this part. For high-temperature applications up to 125°C, select Sullins PBC03 or PEC03 series variants. For applications requiring 130°C operation, the 77313-102-06LF is the appropriate choice.

Q: What is the difference between the 77313-102-06LF contact finish and the Würth 61300621121?

A: The 77313-102-06LF features gold or gold GXT™ mating contact finish with 30.0µin (0.76µm) thickness. The 61300621121 features gold mating contact finish with unspecified thickness. Both use tin-plated posts. The Amphenol part specifies phosphor bronze contact material, while the Würth part specifies copper alloy contact material. Both finishes and materials are acceptable for standard board-to-board interconnection applications.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Current inventory levels vary by part number. The PBC03DAAN (Sullins) has the highest inventory at 8022 pieces. The 77313-102-06LF has 1735 pieces available. The 61300621121 (Würth) has 1890 pieces, and the 826942-3 (TE) has 1431 pieces. For applications with extended lead times or high-volume requirements, the PBC03DAAN variant offers the largest available stock.
