MTS-08 Equivalent & Substitute Parts Reference

Part Overview

The MTS-08 is an 8-position rectangular connector housing manufactured by Adam Tech, designed for 0.100" (2.54mm) pitch applications with crimp-style female socket contacts. This receptacle connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and design updates. The MTS-08 operates across a temperature range of -25°C to 85°C and is RoHS3 compliant with MSL Level 1 rating.

Substitute Part Grouping Explanation

Substitution for the MTS-08 is determined by strict alignment of electrical and mechanical parameters. The critical parameters that define interchangeability are:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 8 positions at 0.100" (2.54mm) spacing
Row Configuration: Single row layout
Mounting & Termination: Free hanging in-line mounting with crimp termination
Environmental Compliance: RoHS3 compliance and MSL Level 1 rating

The substitute parts listed below maintain these core parameters. Variations in insulation material, color, and operating temperature range do not affect functional interchangeability within the specified parameter set.

Engineering Selection Recommendations

MTA-08 (Adam Tech) is the primary substitute for the obsolete MTS-08. Both parts share identical electrical and mechanical specifications, including insulation material, operating temperature range, and color. The MTA-08 is currently in active production with higher inventory availability (5376 units), making it the preferred direct replacement for existing MTS-08 applications.

0050579008 (Molex SL 70066 Series) and 65039-029ELF (Amphenol ICC Mini-PV™ Basics+ Series) are parametric equivalents that maintain all critical functional parameters. Both parts feature extended operating temperature ranges (-40°C to 105°C) and alternative insulation materials. These options are suitable for applications requiring broader environmental performance or specific material properties. Both are RoHS3 compliant with active product status and high inventory availability.

Selection between these three active substitutes should be based on:

Availability requirements and lead time
Color specification (white for MTA-08; black for Molex and Amphenol ICC options)
Extended temperature performance needs
Existing supply chain relationships and qualification status

Frequently Asked Questions (FAQ)

Q: Can the MTA-08 directly replace the MTS-08 in existing designs? A: Yes. The MTA-08 maintains identical electrical and mechanical parameters, including 8-position configuration, 0.100" pitch, crimp termination, and operating temperature range. No design modification is required.

Q: What is the primary difference between the MTS-08 and Molex 0050579008? A: The core functional parameters are equivalent. The Molex part features an extended operating temperature range (-40°C to 105°C versus -25°C to 85°C) and uses glass-filled polyester insulation instead of nylon 6/6. Color is black rather than white.

Q: Are the Amphenol ICC and Molex substitutes interchangeable with each other? A: Yes, within the specified parameter set. Both maintain 8-position, 0.100" pitch receptacle configuration with female socket contacts and crimp termination. Both support the same MSL Level 1 rating and RoHS compliance.

Q: Does insulation material affect connector compatibility? A: Insulation material does not affect mechanical or electrical interchangeability for these rectangular connector housings. Material selection is application-dependent and based on environmental exposure, chemical resistance, or thermal requirements beyond the standard operating range.

Q: Why is the MTS-08 listed as obsolete? A: Obsolete status indicates the part is no longer manufactured by Adam Tech. The MTA-08 from the same manufacturer provides an active production alternative with identical specifications.

Q: Can I use the extended temperature range versions in applications rated only to 85°C? A: Yes. Parts rated for -40°C to 105°C are fully compatible with applications requiring -25°C to 85°C operation. The extended range provides additional design margin without affecting performance in standard temperature applications.

Q: What packaging options are available? A: MTA-08 is supplied in bulk packaging. The Molex 0050579008 is supplied in bulk. The Amphenol ICC 65039-029ELF is supplied in bag packaging. Packaging does not affect connector functionality.
