M20-8760242P Equivalent & Substitute Parts

Part Overview

The M20-8760242P is a surface mount rectangular connector header manufactured by Harwin Inc., featuring 4 positions arranged in 2 rows with 0.100" (2.54mm) pitch. This connector is designed for board-to-board or cable applications with solder termination and push-pull fastening. The part is active in production status and widely used in electronic assemblies requiring reliable interconnection at standard 2.54mm spacing.

Substitute parts are necessary when the original M20-8760242P becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats better suit manufacturing requirements while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

All Samtec TSM-102 series substitute parts maintain full compliance with ROHS3 and REACH requirements, matching the M20-8760242P regulatory status. All parts carry UL94 V-0 flammability certification and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

Selection between substitute options should be based on packaging requirements for your manufacturing process:

TSM-102-02-L-DV (Bulk) and TSM-102-02-T-DV (Bulk) are suitable for applications requiring loose component handling or custom packaging integration.

TSM-102-02-L-DV-A-P-TR (Cut Tape) and TSM-102-02-L-DV-P-TR (Tape & Reel) provide automated pick-and-place compatibility for high-volume surface mount assembly.

TSM-102-02-SM-DV (Tube) matches the original M20-8760242P packaging format for direct replacement in existing supply chains.

TSM-102-02-T-DV-P-TR (Tape & Reel) offers pick-and-place features with tape and reel packaging for automated assembly environments.

Contact finish differences exist between parts: gold-plated mating contacts (TSM-102-02-L-DV, TSM-102-02-L-DV-A-P-TR, TSM-102-02-L-DV-P-TR, TSM-102-02-S-DV-P-TR, TSM-102-02-SM-DV) versus tin-plated mating contacts (TSM-102-02-T-DV, TSM-102-02-T-DV-P-TR). Gold-plated variants provide enhanced corrosion resistance and contact reliability in demanding environments.

Operating temperature ranges for TSM-102-02-L-DV, TSM-102-02-L-DV-A-P-TR, TSM-102-02-L-DV-P-TR, TSM-102-02-S-DV-P-TR, and TSM-102-02-SM-DV extend to -55°C ~ 125°C, exceeding the M20-8760242P specification of -40°C ~ 105°C. TSM-102-02-T-DV and TSM-102-02-T-DV-P-TR maintain the -55°C ~ 105°C range.

Frequently Asked Questions (FAQ)

Q: Can TSM-102 series connectors directly replace M20-8760242P in existing PCB designs?

A: Yes. All substitute parts share identical mating pitch (0.100" / 2.54mm), position count (4), row configuration (2 rows), and connector interface geometry. PCB footprints designed for M20-8760242P are compatible with all listed TSM-102 variants. The increased contact length (0.320" vs. 0.228") in TSM-102 parts does not affect PCB compatibility.

Q: What is the difference between gold-plated and tin-plated contact finishes?

A: Gold-plated mating contacts (TSM-102-02-L-DV series and TSM-102-02-S-DV-P-TR) provide superior corrosion resistance and lower contact resistance over extended service life. Tin-plated mating contacts (TSM-102-02-T-DV series) offer cost efficiency while maintaining electrical performance within standard operating conditions. Both finishes are suitable for general-purpose applications; gold plating is preferred for high-reliability or corrosive environments.

Q: Does the change from Polyamide (PA6T) to Liquid Crystal Polymer (LCP) insulation affect performance?

A: Both materials meet UL94 V-0 flammability requirements and provide adequate insulation for the specified voltage and current ratings. LCP offers superior dimensional stability and lower moisture absorption compared to polyamide, which may benefit applications requiring tight mechanical tolerances or high-humidity environments.

Q: Which packaging format should I select for automated assembly?

A: TSM-102-02-L-DV-A-P-TR (Cut Tape with board guide and pick-and-place features), TSM-102-02-L-DV-P-TR (Tape & Reel with pick-and-place), TSM-102-02-S-DV-P-TR (Tape & Reel with pick-and-place), and TSM-102-02-T-DV-P-TR (Tape & Reel with pick-and-place) are optimized for automated surface mount assembly equipment. Bulk and tube formats require manual handling or custom feeder integration.

Q: Are all substitute parts in active production status?

A: Yes. All listed TSM-102 variants are active production parts from Samtec Inc. with confirmed inventory availability.

Q: What is the significance of the contact length difference (0.228" vs. 0.320")?

A: The longer contact length in TSM-102 parts (0.320") provides increased mating depth and engagement surface compared to the M20-8760242P (0.228"). This does not affect PCB compatibility but may influence connector stack height in applications with multiple mated connectors. Refer to mated stacking height specifications for your specific application requirements.

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

A: Yes. All TSM-102 variants are electrically and mechanically identical at the connector interface. Mixing packaging formats is acceptable from a functional standpoint; however, supply chain and manufacturing process consistency may favor selecting a single packaging variant for a given production run.
