Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTOP034200 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 3 positions with 0.150" (3.81mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors
• Header Configuration: Male pins in unshrouded vertical orientation are required for form-factor compatibility
• Voltage Rating: Minimum 300V UL rating is mandatory for electrical safety equivalence
• Contact Geometry: Contact tail length of 0.138" (3.50mm) ensures proper solder joint formation and PCB penetration depth
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating must be maintained for regulatory and environmental requirements

The substitute part OP0342000000G (Amphenol Anytek) satisfies all critical substitution parameters while offering improved product status (Active) and additional electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OP0342000000G substitute part is functionally equivalent to the OSTOP034200 based on matching critical electrical and mechanical parameters: identical position count, pitch spacing, voltage rating, and contact geometry.

The OP0342000000G offers the additional advantage of Active product status, ensuring long-term availability and supply chain stability compared to the Obsolete OSTOP034200. Both parts maintain equivalent RoHS3 compliance and MSL Level 1 ratings, satisfying regulatory requirements.

The substitute part provides documented electrical specifications (10A current rating, -40°C to 115°C operating temperature range, UL94 V-0 flammability rating) that were not specified for the original part, offering enhanced design documentation for system validation.

Frequently Asked Questions (FAQ)

Q: Can OP0342000000G be used as a direct replacement for OSTOP034200?

A: Yes. Both parts share identical position count (3), pitch spacing (0.150"/3.81mm), header orientation (vertical), pin configuration (male, unshrouded), voltage rating (300V UL), and contact tail length (0.138"/3.50mm). Mechanical and electrical compatibility is established.

Q: What is the primary difference between these parts?

A: The OSTOP034200 is Obsolete, while OP0342000000G maintains Active status. The substitute part provides documented current rating (10A), operating temperature range (-40°C to 115°C), contact finish (Tin), and flammability rating (UL94 V-0) that enhance design specification clarity.

Q: Are there packaging differences between the parts?

A: The OSTOP034200 packaging is not specified in available documentation. The OP0342000000G is supplied in Bulk packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet current compliance standards?

A: Yes. Both the OSTOP034200 and OP0342000000G are RoHS3 Compliant with MSL Level 1 (Unlimited) rating. Both carry REACH Unaffected status and EAR99 ECCN classification.

Q: What inventory status should I consider?

A: The OSTOP034200 shows 847 pieces in stock as new original inventory. The OP0342000000G shows 1044 pieces in stock. For new designs or long-term production, the Active status of OP0342000000G provides superior supply chain assurance.
