MTLW-103-24-T-D-310 Equivalent & Substitute Parts
Part Overview
The MTLW-103-24-T-D-310 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 6-position, 2-row connector operates at 0.100" (2.54mm) pitch and features tin-plated phosphor bronze contacts rated for 5.2A per contact. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable interconnection across a wide operating temperature range of -55°C to 105°C.
Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or address specific application requirements while maintaining functional compatibility within the connector category.

Substitute Part Grouping Explanation
Substitution eligibility for the MTLW-103-24-T-D-310 is determined by the following critical parameters that must align across parts:
- Connector Type: Header (with or without breakaway feature)
- Contact Type: Male Pin
- Pitch - Mating: 0.100" (2.54mm)
- Number of Positions: 6
- Number of Rows: 2
- Row Spacing - Mating: 0.100" (2.54mm)
- Mounting Type: Through Hole
- Termination: Solder
- Fastening Type: Push-Pull
- Contact Shape: Square
- Shrouding: Unshrouded
- Material Flammability Rating: UL94 V-0
- RoHS Status: ROHS3 Compliant
- Product Status: Active
The PRPC003DAAN-RC from Sullins Connector Solutions meets all critical substitution criteria. Variations in contact finish (Gold vs. Tin), contact material (Brass vs. Phosphor Bronze), insulation material (PBT vs. LCP), current rating, and operating temperature range represent acceptable engineering trade-offs within the rectangular connector category for this application class.

Engineering Selection Recommendations
Both the MTLW-103-24-T-D-310 and PRPC003DAAN-RC are Active status products with ROHS3 compliance and UL94 V-0 flammability ratings, qualifying them for equivalent use in rectangular connector applications requiring regulatory compliance.
The MTLW-103-24-T-D-310 provides higher current capacity (5.2A per contact) and extended low-temperature operation (-55°C minimum), making it suitable for high-power or extreme cold environment applications. The PRPC003DAAN-RC offers gold-plated contacts and breakaway header functionality, providing enhanced contact durability and modular assembly options for standard industrial applications.
Selection between these parts should be based on specific application requirements regarding current load, operating temperature extremes, and connector modularity needs.
Frequently Asked Questions (FAQ)
Q: Can PRPC003DAAN-RC replace MTLW-103-24-T-D-310 in all applications?
A: Substitution is valid for applications operating within -40°C to 105°C and requiring maximum 3A per contact. Applications requiring -55°C operation or 5.2A current capacity require the MTLW-103-24-T-D-310.
Q: What is the difference between tin and gold contact finishes?
A: Tin-plated contacts (MTLW-103-24-T-D-310) provide cost-effective performance for standard applications. Gold-plated contacts (PRPC003DAAN-RC) offer superior corrosion resistance and contact reliability in high-reliability or harsh environments.
Q: Does the breakaway feature of PRPC003DAAN-RC affect compatibility?
A: The breakaway feature is an additional capability that does not affect mating compatibility. Both connectors maintain identical pitch, position count, and row spacing.
Q: Are both parts suitable for automated assembly?
A: Both parts feature through-hole solder termination and are compatible with standard PCB assembly processes.
Q: What is the moisture sensitivity level for both parts?
A: Both MTLW-103-24-T-D-310 and PRPC003DAAN-RC carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
