M30-1401200 Equivalent & Substitute Parts

Part Overview

The M30-1401200 is a 12-position rectangular connector receptacle housing manufactured by Harwin Inc., designed for 0.049" (1.25mm) pitch applications with crimp contact termination and friction lock fastening. This part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and design requirements. The housing accommodates female socket contacts and is suitable for free-hanging in-line mounting configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the M30-1401200 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle housing with female socket contacts
Position Count & Pitch: 12 positions at 0.049" (1.25mm) spacing
Mounting & Termination: Free-hanging in-line mounting with crimp termination
Fastening Mechanism: Friction lock engagement system
Compliance & Environmental: ROHS3 compliance and MSL 1 rating

Two substitute parts meet these criteria:

M30-1101200 (Harwin Inc., MFR Recommended): Active product status with identical core electrical and mechanical parameters. Differs in color (natural vs. white) and fastening type specification (not listed vs. friction lock).

0510211200 (Molex PicoBlade 51021 series, Parametric Equivalent): Active product status with matching electrical and mechanical specifications. Differs in insulation material (PBTP vs. unspecified), operating temperature range (-40°C ~ 105°C vs. unspecified), and fastening type confirmation (friction lock).

Engineering Selection Recommendations

M30-1101200 is the manufacturer-recommended substitute, maintaining Harwin Inc. series continuity within the M30 product line. Active product status ensures ongoing availability and supply chain stability. ROHS3 compliance and MSL 1 rating are maintained. Selection of this part is appropriate for applications where manufacturer consistency and established supply relationships are prioritized.

0510211200 is a parametric equivalent from Molex's PicoBlade 51021 series, offering cross-manufacturer substitution capability. Active product status and high inventory availability (78,469 units) support procurement flexibility. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for applications where multi-source qualification and extended operating temperature range (-40°C ~ 105°C) provide design advantages.

Both substitutes are ROHS3 compliant and carry MSL 1 ratings, meeting regulatory and environmental requirements equivalent to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can M30-1101200 and 0510211200 be used interchangeably with M30-1401200?

A: Both parts meet the core electrical and mechanical substitution criteria: 12-position receptacle housing, 0.049" (1.25mm) pitch, female socket contacts, crimp termination, and free-hanging in-line mounting. Mechanical fit and electrical function are equivalent. Color differences (white vs. natural) and insulation material variations do not affect functional substitution.

Q: What is the significance of the fastening type difference?

A: M30-1401200 and 0510211200 both specify friction lock fastening. M30-1101200 does not list fastening type in the provided data. Friction lock is the engagement mechanism for these connector housings; absence of specification does not indicate incompatibility but rather incomplete documentation.

Q: Are there packaging considerations for these substitutes?

A: M30-1401200 packaging is not specified. M30-1101200 is supplied in bulk packaging. 0510211200 is supplied in bulk packaging. Packaging format does not affect functional equivalence; procurement quantities and handling procedures may require adjustment based on bulk supply requirements.

Q: Why is M30-1401200 obsolete while M30-1101200 remains active?

A: Both parts are from the Harwin M30 series with identical electrical and mechanical specifications. The color difference (white vs. natural) and potential design consolidation within the product line may account for the obsolescence status of the white variant. M30-1101200 represents the active continuation of this connector housing specification.

Q: What is the operating temperature range for M30-1401200?

A: Operating temperature range is not provided in the main part data. M30-1101200 does not specify operating temperature. 0510211200 specifies -40°C ~ 105°C. For applications requiring defined temperature performance, 0510211200 provides explicit thermal specifications.
