Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T1M-04-F-SH-L is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Mating pitch (0.039" / 1.00mm)
• Number of positions (4)
• Number of rows (1)
• Mounting type (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Style (Board to Cable/Wire)
• Contact material (Phosphor Bronze)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)
• Moisture sensitivity level (MSL 1)

The identified substitute parts maintain these core parameters, ensuring mechanical and electrical compatibility within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, supporting long-term design continuity and regulatory adherence.

The T1M-04-F-SH-L and T1M-04-F-SH-L-K are both Samtec Micro Mate™ T1M series connectors with identical electrical and mechanical specifications. The T1M-04-F-SH-L-K includes Pick and Place features, which may provide manufacturing advantages in automated assembly environments. Both parts carry specified operating temperature ranges (-55°C ~ 85°C) and current ratings (3.3A per Contact).

The Molex 5019530407 (Pico-Clasp 501953 series) meets all critical substitution parameters including pitch, position count, mounting type, shrouding, and fastening configuration. The primary differences are the contact finish (Tin vs. Gold mating surface) and insulation material (Polyamide/Nylon vs. LCP). Operating temperature and electrical ratings are not specified for the Molex part. The Molex connector includes Solder Retention features.

Selection between these parts should be based on design requirements for contact finish, insulation material thermal performance, and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the T1M-04-F-SH-L be directly replaced with the T1M-04-F-SH-L-K?

A: Yes. Both parts are Samtec Micro Mate™ T1M series connectors with identical pitch (1.00mm), position count (4), mounting type (Surface Mount, Right Angle), shrouding (4 Wall), and electrical specifications. The T1M-04-F-SH-L-K includes Pick and Place features for automated assembly.

Q: Is the Molex 5019530407 a direct substitute for the T1M-04-F-SH-L?

A: The Molex 5019530407 meets the critical mechanical and electrical parameters: 1.00mm pitch, 4 positions, 1 row, surface mount right-angle configuration, shrouded 4-wall design, solder termination, and locking ramp fastening. However, the contact finish differs (Tin vs. Gold mating surface) and the insulation material is Polyamide/Nylon instead of LCP. Operating temperature and current/voltage ratings are not specified for the Molex part. Design validation is required to confirm compatibility with specific application requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by alignment of connector type (Header), contact type (Male Pin), mating pitch (1.00mm), position count (4), row count (1), mounting type (Surface Mount, Right Angle), shrouding (4 Wall), termination (Solder), fastening type (Locking Ramp), contact material (Phosphor Bronze), flammability rating (UL94 V-0), RoHS compliance (ROHS3), and MSL rating (1).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The T1M-04-F-SH-L, T1M-04-F-SH-L-K, and Molex 5019530407 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the difference in insulation height between the main part and the Molex substitute?

A: The T1M-04-F-SH-L and T1M-04-F-SH-L-K have an insulation height of 0.181" (4.60mm), while the Molex 5019530407 has an insulation height of 0.185" (4.70mm). This 0.004" (0.10mm) difference may affect PCB layout and mating clearances in space-constrained applications.

Q: What contact finish options are available across these parts?

A: The T1M-04-F-SH-L and T1M-04-F-SH-L-K feature Gold mating contact finish with Tin post finish. The Molex 5019530407 features Tin mating contact finish with Tin post finish. Contact finish selection impacts corrosion resistance and mating force characteristics.
