Amphenol ICC 77313-152-20LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-152-20LF is an active rectangular connector header designed for through-hole mounting applications. This BERGSTIK® series connector features 20 positions arranged in 2 rows with 0.100" (2.54mm) pitch, supporting board-to-board or cable connections. The connector is manufactured with phosphor bronze contacts finished in gold and tin, rated for 3A per contact across an operating temperature range of -65°C to 130°C. As an active product with full RoHS compliance and MSL 1 rating, substitute parts are identified to provide design flexibility for applications requiring alternative contact lengths, insulation materials, or thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-152-20LF is determined by strict alignment of core electrical and mechanical parameters. All substitute parts must maintain the following critical specifications:

• Position Count & Pitch: 20 positions in 2 rows with 0.100" (2.54mm) mating pitch and row spacing
• Connector Type: Header configuration for board-to-board connection
• Contact Type: Male pin with square contact shape
• Mounting & Termination: Through-hole solder termination
• Shrouding: Unshrouded design
• Fastening: Push-pull mechanism
• Insulation Height: 0.100" (2.54mm)
• RoHS Compliance: Required for all substitutes

The three identified 3M 929 series substitutes (929715-01-10-EU, 929715-01-10-I, 929715-03-10-I) meet these core requirements. Variations exist in contact length specifications, insulation material composition, and thermal operating range, which determine suitability for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

All three 3M 929 series substitutes maintain active product status and full RoHS compliance, meeting baseline regulatory requirements. Selection between substitutes depends on specific application constraints:

929715-01-10-EU: Suitable for applications where REACH unaffected status is required and insulation material composition (PCT) is compatible with design specifications. Operating temperature range of -40°C to 105°C is appropriate for standard industrial environments.

929715-01-10-I: Functionally equivalent to 929715-01-10-EU with identical electrical and mechanical specifications. Insulation material uses glass-filled PBT polyester, providing enhanced mechanical properties. Appropriate for applications requiring improved dimensional stability and mechanical strength.

929715-03-10-I: Differentiated by extended post contact length (0.410" vs. 0.110"), resulting in overall contact length of 0.828" compared to 0.528" for the other 3M variants. This configuration accommodates deeper PCB mounting or applications requiring extended solder post engagement. MSL rating is not applicable due to extended post design.

The primary trade-off between the Amphenol ICC 77313-152-20LF and 3M substitutes involves thermal operating range (77313-152-20LF: -65°C to 130°C versus 929715 series: -40°C to 105°C) and current rating per contact (3A versus 2.5A). Applications operating within the 3M thermal and current specifications can utilize these substitutes without functional degradation.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929715 series directly replace the Amphenol ICC 77313-152-20LF in all applications?

A: Direct replacement is possible when application requirements fall within the 3M thermal operating range (-40°C to 105°C) and current specifications (2.5A per contact). Applications requiring operation below -40°C or above 105°C, or demanding current ratings exceeding 2.5A per contact, require the original Amphenol ICC part.

Q: What is the significance of the different contact post lengths in the 3M variants?

A: The 929715-01-10-EU and 929715-01-10-I feature 0.110" post length, while 929715-03-10-I provides 0.410" post length. Post length determines solder engagement depth on the PCB. The extended post variant accommodates applications with thicker PCBs or where deeper solder joint penetration is required for mechanical robustness.

Q: Are there differences in insulation material between the 3M substitutes?

A: Yes. The 929715-01-10-EU uses polycyclohexylenedimethylene terephthalate (PCT), while 929715-01-10-I and 929715-03-10-I use glass-filled polybutylene terephthalate (PBT) polyester. Both materials meet UL94 V-0 flammability requirements. Glass-filled PBT provides enhanced mechanical properties and dimensional stability.

Q: What is the impact of the lower current rating on the 3M parts?

A: The 3M 929715 series is rated for 2.5A per contact compared to 3A for the Amphenol ICC 77313-152-20LF. Applications operating at or near 3A per contact require the original part. Applications with current demands below 2.5A per contact can utilize the 3M substitutes without derating.

Q: How do the contact finish specifications differ?

A: The Amphenol ICC 77313-152-20LF uses gold-finished mating contacts with tin-finished posts. The 3M 929715 series uses gold finish on both mating contacts and posts. Gold post finish on the 3M parts provides enhanced corrosion resistance compared to tin finish.

Q: What packaging considerations apply to these substitutes?

A: All parts are supplied in bulk packaging. The 77313-152-20LF is available with 1041 pieces in stock, while 3M substitutes offer 2695 pieces (929715-01-10-EU), 1466 pieces (929715-01-10-I), and 1199 pieces (929715-03-10-I) in current inventory.

Q: Are there regulatory compliance differences between the main part and substitutes?

A: The Amphenol ICC 77313-152-20LF carries REACH Affected status, while all 3M 929715 variants are REACH Unaffected. Both maintain RoHS compliance and EAR99 export classification. Applications subject to REACH restrictions may require the 3M substitutes.
