MT336C Equivalent & Substitute Parts

Part Overview

The MT336C is a 6.35mm (0.250", 1/4") stereo phone jack connector manufactured by Switchcraft Inc. as part of the MT-JAX® series. This panel-mount barrel connector features three conductors (TRS configuration) with solder eyelet termination and is designed for headphone and audio applications. The part maintains active product status with 654 units in current inventory. Substitute parts are identified to address packaging preferences, compliance requirements, and inventory availability while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the MT336C is determined by the following critical parameters:

  • Mating diameter: 6.35mm (0.250", 1/4") headphone standard
  • Signal configuration: Stereo (3 Conductor, TRS)
  • Connector gender: Female
  • Mounting type: Panel Mount
  • Termination: Solder Eyelet(s)
  • Contact material composition: Palladium with gold plating
  • Operating temperature range: -20°C ~ 65°C

The MT336CX qualifies as a direct substitute based on identical specifications across all critical parameters. Variations in internal switch count (two switches in MT336C versus three switches in MT336CX) and packaging format do not affect functional compatibility for standard audio jack applications. Compliance status differences are noted for procurement and regulatory considerations.

Engineering Selection Recommendations

Both MT336C and MT336CX maintain active product status and are manufactured by Switchcraft Inc. within the MT-JAX® series. Selection between these parts should be based on the following criteria:

MT336C is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. Current inventory of 654 units supports immediate availability for standard procurement volumes.

MT336CX is the preferred selection for applications requiring ROHS3 compliance. The bulk packaging format and significantly higher inventory level (8056 units) make this part suitable for high-volume production runs and long-term supply chain stability. The three-switch configuration provides additional switching functionality compared to the two-switch design of MT336C.

Both parts are classified as REACH Unaffected and carry identical export classification (EAR99), ensuring consistent regulatory treatment across procurement channels.

Frequently Asked Questions (FAQ)

Q: Can MT336CX replace MT336C in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications for the 6.35mm stereo phone jack function, including mating diameter, TRS signal configuration, contact materials, and operating temperature range. The primary differences are internal switch count and compliance status, which do not affect standard audio jack operation.

Q: What is the difference between the two-switch and three-switch configurations?

A: MT336C features two internal switches while MT336CX features three internal switches. The additional switch in MT336CX provides expanded switching capability for applications requiring more complex contact sequencing during mating and unmating operations.

Q: Does packaging format affect compatibility?

A: No. MT336C is supplied in standard packaging while MT336CX is supplied in bulk packaging. Packaging format does not affect the electrical or mechanical performance of the connector itself and is purely a procurement and logistics consideration.

Q: Which part should be selected for new designs?

A: MT336CX is recommended for new designs due to ROHS3 compliance status and superior inventory availability. This selection ensures regulatory alignment with current environmental standards and provides supply chain resilience through higher stock levels.

Q: Are there any temperature or environmental limitations?

A: Both parts operate within the identical temperature range of -20°C to 65°C. Both are unshielded connectors and carry MSL rating of 1 (Unlimited) or Not Applicable, indicating no moisture sensitivity constraints during storage or handling.
