Substitute Part Grouping Explanation

Substitution for the 77313-802-20 is determined by strict alignment of the following electrical and mechanical parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 20
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header, Breakaway
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): 77313-802-20LF

The 77313-802-20LF is the direct successor to the obsolete 77313-802-20, manufactured by the same supplier (Amphenol ICC) within the same BERGSTIK® series. This part maintains identical mechanical and electrical specifications while offering active product status and RoHS compliance. The LF designation indicates lead-free post finish (Tin instead of Tin-Lead), which aligns with modern manufacturing standards. This is the recommended choice for new designs and legacy system updates.

Secondary Substitutes (Cross-Manufacturer Alternatives):

PBC10DAAN (Sullins Connector Solutions) and 6-146260-0 (TE Connectivity AMPMODU Mod II) provide functionally equivalent alternatives with active product status and RoHS3 compliance. Both maintain the core 2.54mm pitch, 20-position, 2-row configuration with identical mating interface geometry. These options offer broader supply chain availability and competitive pricing.

Conditional Substitutes (Design Verification Required):

Molex 0010897202 (C-Grid 70280 series) and Hirose A1-20PA-2.54DSA(71) are mechanically compatible but feature minor variations in contact length and insulation material composition. These parts maintain the required mating pitch and position count but differ in overall connector height and post length. Selection requires verification that PCB footprint and mating clearances accommodate these dimensional variations.

3M 2300 series headers (2320-6121-TG, 2320-6121-TP, 2320-6121TB) are functionally equivalent but non-RoHS compliant. These parts are suitable for legacy applications where RoHS compliance is not mandated.

Compliance Considerations:

For applications requiring RoHS compliance, select from: 77313-802-20LF, 0010897202, 6-146260-0, A1-20PA-2.54DSA(71), PBC10DAAN, PBC10DABN, or PBC10DACN.

For applications with no RoHS requirement, 3M 2300 series and legacy Amphenol parts remain viable.

Frequently Asked Questions (FAQ)

Q: Can I use PBC10DABN or PBC10DACN as direct replacements for the 77313-802-20?

A: Yes, mechanically and electrically. However, these Sullins parts feature extended contact post lengths (0.230" and 0.320" respectively, compared to 0.135" on the original). Verify that your PCB assembly process and mating connector accommodate the increased post length. The mating interface pitch and position count remain identical.

Q: What is the difference between 77313-802-20 and 77313-802-20LF?

A: The primary difference is the contact post finish. The original uses Tin-Lead (150.0µin thickness), while the LF variant uses Tin (78.7µin thickness). The LF designation also indicates RoHS compliance. Both maintain identical mating interface specifications and are mechanically interchangeable.

Q: Are the 3M 2300 series headers compatible with the 77313-802-20 footprint?

A: Yes. The 2320-6121-TG, 2320-6121-TP, and 2320-6121TB all maintain the 2.54mm pitch, 20-position, 2-row configuration with identical mating geometry. However, these parts are RoHS non-compliant and should only be used in applications where RoHS compliance is not required.

Q: Which substitute offers the best supply chain availability?

A: PBC10DAAN (Sullins) currently shows the highest inventory (3,613 pcs), followed by 0010897202 (Molex, 3,227 pcs) and 77313-802-20LF (Amphenol ICC, 1,820 pcs). Availability varies by distributor and region.

Q: Can I mix different substitute parts in the same assembly?

A: All listed substitutes are mechanically and electrically compatible with each other due to standardized 2.54mm pitch and mating interface geometry. However, for consistency and traceability, use a single part number across an assembly.

Q: What is the operating temperature range for each substitute?

A: Operating temperature ranges vary: 77313-802-20LF (-65°C to 130°C), 0010897202 (not specified), 2320-6121-TG and variants (-55°C to 105°C), 6-146260-0 (-65°C to 105°C), A1-20PA-2.54DSA(71) (-55°C to 85°C), and Sullins PBC10 series (-65°C to 125°C). Select based on your application's thermal requirements.

Q: Is the Hirose A1-20PA-2.54DSA(71) a suitable replacement?

A: Yes, with design verification. This part maintains the required mating pitch and position count but features a 200V voltage rating (not specified on the original) and operates within -55°C to 85°C. The contact material is Brass rather than Phosphor Bronze. Verify compatibility with your application's voltage and temperature requirements.
