Engineering Selection Recommendations

The MTSW-104-22-L-S-393 maintains Active product status with established supply availability. Component selection should prioritize parts meeting identical specifications across all electrical, mechanical, and compliance parameters. The part's ROHS3 compliance and UL94 V-0 flammability rating establish baseline requirements for any substitute selection. Active product status ensures continued manufacturer support and supply chain stability. When evaluating alternatives, confirm that all specified parameters remain unchanged to maintain design integrity and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MTSW-104-22-L-S-393?

A: A substitute part must match all electrical parameters (contact type, number of positions, pitch, current rating, operating temperature), all mechanical parameters (mounting type, contact lengths, insulation height, contact shape), and all compliance certifications (UL94 V-0, ROHS3 compliance).

Q: Can parts with different pitch specifications be used as substitutes?

A: No. The 0.100" (2.54mm) mating pitch is a critical mechanical parameter. Parts with different pitch values are not compatible and cannot be substituted.

Q: Are there restrictions on contact finish variations?

A: Yes. The specified gold mating finish and tin post finish are required for electrical performance and reliability. Substitutes must maintain these exact finish specifications.

Q: What is the significance of the "Cuttable" connector type designation?

A: The cuttable designation indicates the connector can be separated into individual positions. This feature must be preserved in any substitute part to maintain design flexibility.

Q: Does the insulation material specification affect substitution eligibility?

A: Yes. The polyester, glass-filled insulation material is specified for mechanical strength and thermal performance. Substitute parts must use identical insulation material composition.

Q: How does the through-hole mounting requirement impact substitute selection?

A: Through-hole mounting is a critical mechanical parameter. Only parts designed for through-hole PCB mounting are compatible. Surface-mount alternatives are not acceptable substitutes.

Q: What role does the UL94 V-0 flammability rating play in substitution?

A: The UL94 V-0 rating is a compliance requirement. Substitute parts must maintain this minimum flammability rating to meet regulatory and safety standards.

Q: Is ROHS3 compliance mandatory for substitutes?

A: Yes. ROHS3 compliance is a regulatory requirement. All substitute parts must maintain ROHS3 compliance status.
