Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP244200 is determined by the following critical parameters:

• Position Count & Pitch: 24 positions at 0.150" (3.81mm) spacing (non-negotiable for mechanical and electrical compatibility)
• Header Configuration: Male pins, unshrouded, vertical orientation
• Voltage Rating: Minimum 300V UL compliance
• Contact Geometry: Tail length 0.138" (3.50mm) and insulation height compatibility
• Compliance: ROHS3 and MSL 1 ratings
• Mounting Interface: Solder or through-hole termination acceptable for PCB integration

The substitute part OP2442000000G (Amphenol Anytek) meets all critical substitution criteria while offering active product status and enhanced operational specifications.

Engineering Selection Recommendations

The OP2442000000G from Amphenol Anytek is the qualified substitute for the obsolete OSTOP244200. Selection rationale is based on:

• Electrical Equivalence: Identical 24-position configuration, 0.150" (3.81mm) pitch, and 300V UL voltage rating ensure direct functional replacement in circuit applications.
• Mechanical Compatibility: Matching contact tail length (0.138" / 3.50mm) and vertical male pin unshrouded design maintain PCB footprint compatibility.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, satisfying environmental and reliability requirements.
• Product Lifecycle: The substitute part carries active product status, ensuring long-term availability and supply chain continuity compared to the obsolete original.
• Enhanced Specifications: The substitute provides specified operating temperature range (-40°C ~ 115°C), current rating (10A UL), and material flammability rating (UL94 V-0), offering documented performance parameters beyond the original specification.

Frequently Asked Questions (FAQ)

Q: Can OP2442000000G directly replace OSTOP244200 on existing PCBs?

A: Yes. Both parts share identical position count (24), pitch (0.150" / 3.81mm), contact tail length (0.138" / 3.50mm), and vertical male pin unshrouded configuration. PCB footprints are mechanically compatible. The mounting interface difference (solder vs. through-hole) does not affect electrical performance or mechanical fit.

Q: What is the difference between the housing materials?

A: OSTOP244200 uses brass housing; OP2442000000G uses thermoplastic housing. Both materials are suitable for terminal block applications and do not affect electrical performance or voltage rating (300V UL for both). Material selection is determined by manufacturing process and cost optimization.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. The substitute provides additional documented specifications including UL94 V-0 flammability rating and operating temperature range (-40°C ~ 115°C), which were not specified for the original part.

Q: Why is the original part obsolete?

A: OSTOP244200 is classified as obsolete by On Shore Technology Inc. The OP2442000000G represents the active equivalent from Amphenol Anytek, ensuring procurement availability and supply chain continuity for new designs and legacy system support.

Q: What is the current rating difference?

A: OP2442000000G specifies 10A UL current rating. The original OSTOP244200 does not provide a current specification. Both parts maintain 300V UL voltage rating. Current capacity should be verified against application requirements.
