Key Parameters

Substitute Part Grouping Explanation

The substitute part 0761451618 is classified as a direct equivalent based on the following criteria:

Electrical Parameters Match:

• Identical number of positions (288)
• Identical pitch (0.053" / 1.35mm)
• Identical voltage rating (30V)
• Identical contact layout (96 differential pairs)
• Identical contact finish and thickness (Gold, 30.0µin)

Mechanical Parameters Match:

• Identical connector type (Header, Male Pins)
• Identical mounting configuration (Through Hole, Press-Fit)
• Identical row and column configuration (18 rows × 16 columns)
• Identical color (Black)

Environmental & Compliance Parameters Match:

• Identical operating temperature range (-55°C ~ 85°C)
• Identical flammability rating (UL94 V-0)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1)

The primary distinction is product status: the main part (0761450618) is obsolete, while the substitute (0761451618) maintains active status with improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761451618 is a direct functional equivalent to the 0761450618 for all electrical and mechanical applications. Selection between these parts should be based on the following factors:

For New Designs and Procurement: Use part number 0761451618. This part maintains active product status with Molex, ensuring long-term availability and supply chain stability. It carries identical ROHS3 compliance and UL94 V-0 flammability certification, meeting all regulatory requirements. The tray packaging format is standard for production environments.

For Legacy System Support: The 0761450618 remains functionally compatible with existing designs due to complete parameter equivalence. However, procurement should transition to 0761451618 as inventory of the obsolete part depletes. Both parts are REACH unaffected and carry identical electrical performance specifications.

Compliance Considerations: Both parts satisfy ROHS3 compliance requirements and maintain UL94 V-0 material flammability ratings. No additional qualification is required when substituting between these part numbers within the same application.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0761451618 as a direct replacement for 0761450618 in existing assemblies?

A: Yes. The 0761451618 is a direct functional equivalent. All electrical parameters (voltage rating, contact configuration, pitch), mechanical parameters (mounting type, termination method, dimensions), and environmental specifications (operating temperature, flammability rating) are identical. No design changes are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0761450618 is obsolete and supplied in bulk packaging, while the 0761451618 is an active product supplied in tray packaging. All technical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical ROHS3 compliance status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Both are REACH unaffected. No additional certifications or testing is required when substituting between these parts.

Q: Why should I transition from 0761450618 to 0761451618?

A: The 0761450618 is classified as obsolete, which means Molex has discontinued active production and support. Transitioning to the active equivalent 0761451618 ensures continued availability, supply chain reliability, and manufacturer support for future procurement needs.

Q: Are the packaging formats interchangeable?

A: Yes, from a functional standpoint. The 0761450618 uses bulk packaging while the 0761451618 uses tray packaging. Both formats contain the same connector with identical specifications. Tray packaging is standard for production environments and offers improved handling and organization.

Q: What is the contact pitch and how does it affect compatibility?

A: Both parts use a 0.053" (1.35mm) pitch with 288 positions arranged in an 18×16 configuration. This pitch is fixed for the Impact 76145 series and is identical between both part numbers, ensuring complete mechanical and electrical compatibility.
