T1M-04-T-SH-L Equivalent & Substitute Parts

Part Overview

The T1M-04-T-SH-L is a surface mount, right-angle rectangular connector header manufactured by Samtec Inc. as part of the Micro Mate™ T1M series. This 4-position connector operates at 0.039" (1.00mm) pitch and is designed for board-to-cable/wire applications with shrouded construction and solder termination. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.039" (1.00mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Material: Phosphor Bronze
• Contact Finish: Tin (both mating and post)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part 5019530407 (Molex Pico-Clasp 501953) meets all critical dimensional and electrical interface requirements. Both parts feature identical pitch, position count, mounting orientation, and shrouding configuration, ensuring mechanical and electrical compatibility in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

Both the T1M-04-T-SH-L and 5019530407 maintain Active product status and ROHS3 compliance. The primary distinction lies in insulation material composition: the Samtec part uses Liquid Crystal Polymer (LCP) while the Molex substitute employs Polyamide (PA) Nylon. Both materials achieve UL94 V-0 flammability rating.

Insulation height differs marginally (0.181" versus 0.185"), representing a 0.004" (0.10mm) variation within typical manufacturing tolerances for this connector class. The Molex part includes documented solder retention feature.

Selection between these parts should be based on material compatibility requirements specific to the application environment, packaging format availability (Tape & Reel for Molex), and inventory status. Both parts satisfy the core electrical and mechanical interface requirements for board-to-cable/wire connectivity at 1.00mm pitch with 4-position shrouded configuration.

Frequently Asked Questions (FAQ)

Q: Are T1M-04-T-SH-L and 5019530407 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.039" / 1.00mm), position count (4), row configuration (1), mounting type (surface mount right angle), and shrouding design (4-wall shrouded). The 0.004" insulation height difference does not affect mechanical fit in standard PCB applications.

Q: What is the primary difference between these two parts?

A: The insulation material differs: T1M-04-T-SH-L uses Liquid Crystal Polymer (LCP), while 5019530407 uses Polyamide (PA) Nylon. Both achieve UL94 V-0 flammability rating. The Molex part specifies solder retention feature.

Q: Can I substitute 5019530407 for T1M-04-T-SH-L in existing designs?

A: Substitution is viable for applications where the insulation material change from LCP to PA Nylon is acceptable. Both parts maintain identical electrical interface characteristics, contact configuration, and compliance certifications (ROHS3, UL94 V-0, MSL 1).

Q: What packaging formats are available?

A: The Samtec T1M-04-T-SH-L packaging format is not specified in available documentation. The Molex 5019530407 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are operating temperature and current ratings identical?

A: The T1M-04-T-SH-L specifies -55°C to 85°C operating temperature and 3.3A per contact current rating. The Molex 5019530407 does not provide these specifications in available documentation. For applications requiring confirmed thermal and current performance, reference the T1M-04-T-SH-L datasheet.

Q: Do both parts comply with RoHS requirements?

A: Yes. Both T1M-04-T-SH-L and 5019530407 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
