Key Parameters

Substitute Part Grouping Explanation

Substitution within the MMT-103 series is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (3), mating pitch (2.00mm), mounting configuration (surface mount, right angle), termination method (solder), current rating (3A), operating temperature range (-55°C to 125°C), contact finish (gold mating surface), insulation material (LCP), and compliance certifications (ROHS3, UL94 V-0).

The MMT-103-02-L-SH-P-TR differs from its substitute counterpart only in the fastening type designation within the part number suffix. Both parts maintain identical electrical performance, mechanical dimensions, and environmental ratings. Substitution is valid when these core parameters remain unchanged across the connector application.

Parameter Comparison

Engineering Selection Recommendations

Both MMT-103-02-L-SH-P-TR and MMT-103-02-L-SH-K-TR are active production parts with identical compliance certifications. Selection between these parts is based on availability and inventory status. The MMT-103-02-L-SH-K-TR currently maintains 784 pieces in stock compared to 769 pieces for the primary part number. Both parts satisfy ROHS3 compliance requirements and UL94 V-0 flammability standards. No technical differentiation exists between these connectors for standard board-to-board or cable applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are MMT-103-02-L-SH-P-TR and MMT-103-02-L-SH-K-TR electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 3A current rating, gold-plated mating contacts, phosphor bronze contact material, and operating temperature range of -55°C to 125°C.

Q: What is the difference between the P and K designations in the part numbers?

A: The P and K suffixes indicate different fastening type classifications within the MMT-103 series. All other mechanical and electrical parameters remain identical.

Q: Can these connectors be used in high-temperature applications?

A: Both parts operate across -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.

Q: Are both parts available in the same packaging format?

A: Yes. Both MMT-103-02-L-SH-P-TR and MMT-103-02-L-SH-K-TR are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the mating pitch specification for these connectors?

A: The mating pitch is 0.079 inches (2.00mm) for both parts, maintaining 3-position contact spacing.

Q: Do these connectors meet RoHS compliance requirements?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification.
