Key Parameters

Substitute Part Grouping Explanation

The T1M-03-F-SV-L-P qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Series Match: Both parts belong to the Micro Mate™ T1M series
• Position Count: Identical 3-position configuration
• Pitch Specification: Both maintain 0.039" (1.00mm) mating pitch
• Connector Type & Contact Type: Both are Header connectors with Male Pin contacts
• Mounting & Termination: Both use Surface Mount with Solder termination
• Electrical Ratings: Identical current (3.3A per Contact) and voltage ratings (250VAC, 353VDC)
• Operating Temperature Range: Identical -55°C ~ 85°C specification
• Mechanical Design: Both feature Shrouded 4-Wall design with Locking Ramp fastening
• Material & Compliance: Both use Liquid Crystal Polymer (LCP) insulation with UL94 V-0 rating and ROHS3 compliance

The primary difference is the contact finish on the mating surface: the substitute part features Gold plating (3.00µin thickness) compared to Tin on the original part. This represents an enhancement in corrosion resistance and contact reliability.

Parameter Comparison

Engineering Selection Recommendations

The T1M-03-F-SV-L-P is the appropriate substitute for the obsolete T1M-03-T-SV-L-P. Selection is based on the following engineering factors:

Product Status: The substitute part maintains Active status, ensuring continued availability and manufacturing support from Samtec Inc., whereas the original part is Obsolete.

Compliance & Certifications: Both parts maintain identical compliance certifications including ROHS3 compliance, UL94 V-0 flammability rating, and Moisture Sensitivity Level 1 (Unlimited). No compliance degradation occurs with substitution.

Electrical & Mechanical Compatibility: All critical electrical parameters (current rating, voltage rating, operating temperature range) and mechanical specifications (pitch, position count, mounting type, termination method) are identical between the two parts.

Contact Finish Enhancement: The substitute part features Gold plating on mating contacts compared to Tin on the original part. This represents a material upgrade that improves corrosion resistance and contact reliability without introducing incompatibility.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Are T1M-03-T-SV-L-P and T1M-03-F-SV-L-P mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including pitch (1.00mm), position count (3), mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), and fastening method (Locking Ramp). They are designed for the same PCB footprint and mating interface.

Q: What is the difference between the "T" and "F" designations in the part numbers?

A: The "T" in T1M-03-T-SV-L-P indicates Tin contact finish on the mating surface. The "F" in T1M-03-F-SV-L-P indicates Gold contact finish on the mating surface. Both finishes are applied to Phosphor Bronze base material.

Q: Will the Gold-plated substitute part affect circuit performance?

A: No. The Gold plating (3.00µin thickness) on the mating contacts does not alter electrical performance. Both parts maintain identical current rating (3.3A per Contact) and voltage rating (250VAC, 353VDC). Gold plating provides enhanced corrosion resistance and contact reliability.

Q: Is the substitute part RoHS compliant?

A: Yes. The T1M-03-F-SV-L-P is ROHS3 compliant, matching the compliance status of the original part.

Q: What packaging is available for the substitute part?

A: The T1M-03-F-SV-L-P is supplied in Tape & Reel (TR) packaging, which is standard for surface mount assembly operations and provides efficient handling for automated pick-and-place equipment.

Q: Can I use the substitute part in existing designs without PCB modification?

A: Yes. The substitute part is mechanically and electrically compatible with the original part. No PCB redesign or modification is required.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 85°C, ensuring thermal compatibility in all specified applications.
