OSTOP234200 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTOP234200 is a 23-position terminal block header manufactured by On Shore Technology Inc., designed for vertical solder mounting applications with 0.150" (3.81mm) pitch spacing. This component features male pins in an unshrouded configuration and is rated for 300V UL operation. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP234200 is determined by strict alignment of the following critical parameters:

• Position Count: 23 positions (non-negotiable)
• Pitch Spacing: 0.150" (3.81mm) (non-negotiable)
• Header Orientation: Vertical configuration
• Pin Configuration: Male pins, unshrouded
• Voltage Rating: 300V UL minimum
• Mounting Interface: Solder or through-hole compatible with PCB footprint
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The substitute part OP2342000000G manufactured by Amphenol Anytek meets all critical electrical and mechanical parameters. While this substitute employs through-hole mounting rather than surface solder mounting, the identical pitch, position count, voltage rating, and physical dimensions (contact tail length and insulation height) ensure functional equivalence in applications where the PCB footprint accommodates through-hole termination.

Parameter Comparison

Engineering Selection Recommendations

The OP2342000000G from Amphenol Anytek is a functionally equivalent substitute for the obsolete OSTOP234200 based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical voltage ratings (300V UL), position count (23), and pitch spacing (0.150" / 3.81mm). The substitute provides additional current specification (10A UL) not documented for the original part.

Mechanical Compatibility: Contact tail length and overall vertical orientation are identical. The insulation height difference (0.138" vs. 0.079") reflects design variation between manufacturers but does not affect functional compatibility provided the PCB footprint accommodates the through-hole mounting method.

Regulatory Status: Both components are ROHS3 compliant and carry EAR99 classification, ensuring equivalent compliance posture for export and environmental regulations.

Production Status: The substitute is in active production with documented inventory availability (906 pcs), whereas the original part is obsolete. This transition to an active equivalent ensures long-term supply chain continuity.

Critical Consideration: The primary design difference is the mounting method (solder vs. through-hole). PCB redesign or rework may be required if the original design specifies surface-mount solder termination. Verification of PCB footprint compatibility is necessary before implementation.

Frequently Asked Questions (FAQ)

Q: Can OP2342000000G be used as a direct drop-in replacement for OSTOP234200?

A: Electrical and mechanical parameters are equivalent. However, the mounting method differs (through-hole vs. solder). Direct substitution is possible only if the PCB footprint supports through-hole termination. If the original design requires solder mounting, PCB modification is necessary.

Q: What is the significance of the insulation height difference (0.138" vs. 0.079")?

A: The insulation height difference reflects design variation between manufacturers. This does not affect electrical performance or voltage rating. Physical clearance on the PCB should be verified to ensure the lower profile of the substitute does not create interference issues.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and classified as EAR99. No compliance disadvantage exists with the substitute.

Q: Why is the housing material different (Brass vs. Thermoplastic)?

A: Housing material variation is common among equivalent terminal block designs from different manufacturers. Both materials provide adequate electrical insulation and mechanical support for this application. The thermoplastic housing of the substitute is suitable for the specified voltage and current ratings.

Q: Is the 10A current rating of the substitute a limiting factor?

A: The original OSTOP234200 does not specify a current rating. The OP2342000000G specifies 10A UL, which represents the maximum safe current per contact. System design should verify that actual current requirements do not exceed this specification.

Q: What inventory considerations apply to this substitution?

A: The OSTOP234200 is obsolete with limited remaining stock (1045 pcs). The OP2342000000G is in active production with current inventory (906 pcs). For new designs or long-term support, the active substitute is the recommended choice.
