Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334724851 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (8)
Pitch specification (0.138" / 3.50mm)
Number of rows (2)
Mounting type (Free Hanging, In-Line)

Engineering Selection Recommendations

Functional Interchangeability: The Molex 0334724801 is functionally equivalent to the 0334724851 across all critical connector interface parameters. Both parts share identical specifications for position count, pitch, row configuration, mounting method, contact termination, and fastening mechanism. Selection between these parts may be based on the following factors:

Packaging Considerations: The 0334724801 is supplied in bulk packaging, whereas the 0334724851 packaging format is not specified. Bulk packaging may be advantageous for high-volume production environments or when reel-based component handling systems are employed.

Inventory Availability: The 0334724801 maintains significantly higher inventory levels (2483 pieces) compared to the 0334724851 (678 pieces), supporting extended procurement windows and reducing lead-time risk.

Regulatory Compliance: The 0334724801 carries explicit RoHS3 compliance certification and REACH unaffected status, providing documented regulatory alignment for applications subject to these requirements. The 0334724851 does not specify these certifications.

Environmental Specifications: The 0334724801 provides a defined operating temperature range of -40°C to 150°C and specifies MSL 1 (Unlimited) moisture sensitivity classification. The 0334724851 does not provide these environmental specifications.

Both parts are active products from Molex within the MX150 33472 series and are suitable for direct substitution in applications requiring 8-position, 3.50mm pitch rectangular connector receptacle housings with sealed, latch-holder fastened construction.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334724801 be used as a direct replacement for the 0334724851 in existing designs?

A: Yes. The 0334724801 is functionally equivalent to the 0334724851 across all connector interface specifications, including position count, pitch, row configuration, mounting type, contact termination, and fastening mechanism. No design modifications are required for substitution.

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

A: The primary differences are packaging format (bulk for 0334724801 versus unspecified for 0334724851), insulation material composition, documented operating temperature range, and regulatory certifications. The 0334724801 provides explicit RoHS3 compliance and REACH unaffected status, while the 0334724851 does not specify these certifications.

Q: Are the insulation materials compatible for the same application?

A: Both parts utilize glass-filled polymer insulation materials suitable for the MX150 33472 series. The 0334724851 specifies Syndiotactic Polystyrene (SPS) glass-filled material, while the 0334724801 specifies Polyamide (PA) nylon glass-filled material with Syndiotactic Polystyrene (SPS) as an alternative. Material selection does not affect connector interface compatibility.

Q: Does the bulk packaging of the 0334724801 affect its performance compared to the 0334724851?

A: No. Packaging format does not affect connector performance or electrical/mechanical characteristics. Bulk packaging is a supply chain consideration and may be preferred for high-volume manufacturing environments.

Q: What is the significance of the MSL 1 (Unlimited) rating on the 0334724801?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to assembly. This simplifies supply chain management and reduces component preparation requirements.

Q: Can I use the 0334724851 if RoHS3 compliance is required?

A: The 0334724851 does not specify RoHS3 compliance status. For applications with explicit RoHS3 compliance requirements, the 0334724801 is the documented compliant alternative within this product family.

Q: Are both parts suitable for sealed connector applications?

A: Yes. Both the 0334724851 and 0334724801 feature sealed construction and are suitable for applications requiring environmental protection and sealed connector housings.

Q: What is the base product number for both parts?

A: Both parts share the base product number 033472, indicating they belong to the same connector family within the MX150 33472 series.
