MTS-09 Equivalent & Substitute Parts Reference

Part Overview

The MTS-09 is a 9-position rectangular connector housing manufactured by Adam Tech, designed for receptacle applications with 0.100" (2.54mm) pitch spacing. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The MTS-09 accepts female socket contacts via crimp termination and operates across a temperature range of -25°C to 85°C. Substitute parts must maintain compatibility with the same pitch, position count, contact type, and termination method while meeting current RoHS3 and REACH compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTS-09 are qualified based on strict parametric equivalence in the following critical areas:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (9)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Free Hanging / In-Line)
• Contact termination method (Crimp)

Compliance Requirements:

• RoHS3 compliance
• MSL rating of 1 or better
• REACH unaffected status

Substitute parts may differ in insulation material composition, color, operating temperature range, and manufacturer series designation, provided all mandatory parameters remain identical. These variations do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

MTA-09 (Adam Tech): This part is the primary substitute for the obsolete MTS-09. Both components share identical electrical and mechanical specifications, including insulation material, operating temperature range, and color. The MTA-09 maintains active product status with higher inventory availability (2904 units), ensuring procurement reliability. This part is recommended as the first-choice replacement.

0050579009 (Molex SL 70066 Series): This Molex connector provides parametric equivalence across all mandatory functional parameters. The extended operating temperature range (-40°C to 105°C) exceeds MTS-09 specifications. The insulation material differs (polyester, glass-filled versus polyamide), and the housing color is black rather than white. This part is suitable for applications where the extended temperature capability is beneficial or where color differentiation is acceptable. Inventory availability is substantial (24231 units).

0050579309 (Molex SL 70066 Series): This alternative Molex part maintains identical functional compatibility with the MTS-09 across all critical parameters. It shares the same extended operating temperature range and alternative insulation material as the 0050579009. Inventory availability is lower (1039 units) compared to other substitutes. Selection between 0050579009 and 0050579309 should be based on specific application requirements and procurement lead time considerations.

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL rating of 1, meeting current regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the MTA-09 be used as a direct replacement for the MTS-09?

A: Yes. The MTA-09 is a direct functional equivalent. Both parts share identical specifications for connector type, contact type, position count, pitch, mounting type, termination method, insulation material, and operating temperature range. The primary difference is product status: MTA-09 is active while MTS-09 is obsolete.

Q: What are the differences between Adam Tech and Molex substitutes?

A: Adam Tech substitutes (MTA-09) maintain identical insulation material (polyamide/nylon) and operating temperature range (-25°C to 85°C) as the original MTS-09. Molex substitutes (0050579009 and 0050579309) feature polyester glass-filled insulation and an extended operating temperature range (-40°C to 105°C). All parts maintain the same electrical and mechanical interface specifications.

Q: Does housing color affect interchangeability?

A: Housing color does not affect electrical or mechanical interchangeability. The MTS-09 and MTA-09 are white; the Molex parts are black. Color selection should be based on application requirements, assembly identification, or design preferences.

Q: Are the Molex parts (0050579009 and 0050579309) interchangeable with each other?

A: Yes. Both Molex parts are functionally identical across all electrical and mechanical parameters. They belong to the same SL 70066 series and differ only in inventory availability and HTSUS classification. Selection between them should be based on procurement considerations and lead time requirements.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (unlimited moisture sensitivity level). These certifications ensure compatibility with current regulatory and environmental standards.

Q: Can I use these substitutes in applications requiring the original -25°C to 85°C temperature range?

A: Yes. All substitute parts operate within or exceed the original MTS-09 temperature specification. The Molex substitutes provide extended capability (-40°C to 105°C), making them suitable for wider temperature applications.

Q: Are contacts included with these connector housings?

A: No. All parts listed (MTS-09, MTA-09, 0050579009, and 0050579309) are housings only. Female socket contacts must be procured separately and installed via crimp termination.
