Engineering Selection Recommendations
Direct Amphenol ICC Replacement: The 77313-101-22LF is the direct successor to the obsolete 77313-101-22. Both share identical pitch, position count, and contact geometry. The LF variant achieves RoHS compliance and extends operating temperature to -65°C ~ 130°C. This part is recommended for designs requiring Amphenol ICC compatibility and RoHS certification.
Cross-Manufacturer Alternatives:
3M 2322-6121-TG: Active product with identical pitch and position configuration. Operates at -55°C ~ 105°C with 3A current rating. Uses glass-filled thermoplastic insulation and tin-lead post finish. Suitable for applications not requiring extended temperature range or RoHS compliance.
TE Connectivity 6-146257-1: Active AMPMODU Mod II series header with matching electrical specifications. Operates at -65°C ~ 105°C with RoHS compliance. Uses liquid crystal polymer insulation and achieves 3A current rating. Insulation height is 0.090" versus standard 0.100", requiring board layout verification.
Sullins Connector Solutions PBC11 Series: Multiple variants (DAAN, DABN, DACN, DADN, DAEN, DAFN, DAHN) provide post length options from 0.120" to 0.820" for varying PCB stack-up requirements. All variants feature phosphor bronze contacts, PBT insulation, ROHS3 compliance, and -65°C ~ 125°C operating range with 3A current rating. Selection depends on required post length for board thickness accommodation.
Compliance Considerations:
- RoHS-compliant designs require 77313-101-22LF, 6-146257-1, or PBC11 series variants
- Non-compliant legacy designs may use 2322-6121-TG or original 77313-101-22 if inventory available
- All active substitutes maintain UL94 V-0 flammability rating
Post Length Selection for PBC11 Series:
- PBC11DAAN: 0.120" post (shallow PCB mounting)
- PBC11DABN: 0.230" post (standard depth)
- PBC11DACN: 0.320" post (moderate depth)
- PBC11DADN: 0.420" post (increased depth)
- PBC11DAEN: 0.520" post (deep mounting)
- PBC11DAFN: 0.620" post (very deep mounting)
- PBC11DAHN: 0.820" post (maximum depth)
Frequently Asked Questions (FAQ)
Q: Can I use 77313-101-22LF as a direct replacement for 77313-101-22? A: Yes. Both parts share identical pitch (0.100"), position count (22), row configuration (2), contact geometry, and mating contact length (0.230"). The LF variant adds RoHS compliance and extends operating temperature range. No board redesign is required.
Q: What is the difference between the Sullins PBC11 variants? A: All PBC11 variants maintain identical electrical and mating specifications. The suffix letter designates post length: DAAN through DAHN provide post lengths from 0.120" to 0.820". Selection is determined by PCB thickness and required solder joint depth. Verify your board stack-up thickness before selection.
Q: Is the TE Connectivity 6-146257-1 compatible with the original 77313-101-22? A: Electrically and mechanically compatible for mating and signal integrity. The insulation height is 0.090" versus 0.100" on the original. Verify board layout clearances and mounting hole spacing before implementation.
Q: Which substitute offers the best RoHS compliance? A: The Sullins PBC11 series (all variants) and TE Connectivity 6-146257-1 carry ROHS3 compliance. Amphenol ICC 77313-101-22LF carries RoHS Compliant status. The 3M 2322-6121-TG is RoHS non-compliant.
Q: Can I mix different PBC11 variants on the same board? A: Yes, if application requirements permit. All PBC11 variants are electrically and mechanically interchangeable. Mixing variants allows accommodation of different component stack heights or mounting depths on a single PCB.
Q: What is the current rating for these connectors? A: The original 77313-101-22 does not specify current rating. All active substitutes (77313-101-22LF, 2322-6121-TG, 6-146257-1, and PBC11 series) are rated at 3A per contact.
Q: Are these connectors suitable for high-temperature applications? A: The 77313-101-22LF supports -65°C ~ 130°C, the highest range among substitutes. The PBC11 series supports -65°C ~ 125°C. The 3M 2322-6121-TG and TE Connectivity 6-146257-1 support -55°C ~ 105°C and -65°C ~ 105°C respectively. Select based on application temperature requirements.
Q: What contact material is used in each substitute? A: Amphenol ICC (77313-101-22 and 77313-101-22LF) and Sullins PBC11 series use phosphor bronze contacts. 3M 2322-6121-TG and TE Connectivity 6-146257-1 use copper alloy contacts. Both materials provide equivalent electrical performance and reliability.
