BL300-02-A Equivalent & Substitute Parts

Part Overview

The BL300-02-A is a 2-position solid state lighting connector manufactured by GCT, designed for board-to-cable/wire applications with poke-in wire termination. This surface mount, right-angle receptacle operates at 300V with a 4A current rating and accommodates 22-24 AWG wire at 0.094" (2.40mm) pitch. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BL300-02-A is determined by the following critical parameters:

• Position Count: Must be 2-position to maintain circuit topology
• Connector Type: Must be receptacle with poke-in wire capability for mechanical compatibility
• Mounting Configuration: Must be surface mount, right-angle orientation
• Termination Method: Must be solder-based for PCB integration
• Pitch Tolerance: Acceptable range is 0.094" to 0.098" (2.40mm to 2.50mm) to accommodate standard wire spacing
• Wire Gauge Compatibility: Must support 22-24 AWG minimum; wider ranges are acceptable
• Electrical Ratings: Substitute must meet or exceed 300V voltage and 4A current requirements
• Compliance: Must maintain ROHS3 compliance and EAR99 classification

The Phoenix Contact 1814634 qualifies as a substitute based on these criteria, with the exception of voltage rating (150V vs. 300V), which represents a design constraint requiring application-level verification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1814634 is an active product with current manufacturing status and full ROHS3 compliance, providing supply continuity for the obsolete BL300-02-A. Mechanical and electrical compatibility is established across position count, connector type, mounting configuration, and termination method.

The primary design consideration is the voltage rating differential: the BL300-02-A is rated 300V while the 1814634 is rated 150V. This 50% reduction in voltage specification requires circuit-level analysis to confirm acceptability within the target application. If the application operates below 150V, the substitute is directly compatible. If operation at or above 150V is required, the voltage rating mismatch disqualifies this substitute.

Secondary considerations include the 0.004" pitch variance (2.40mm vs. 2.50mm) and housing material difference (LCP vs. PA/Nylon). The pitch variance is within standard manufacturing tolerance for connector spacing. The material change from LCP to polyamide may affect thermal performance and chemical resistance depending on environmental exposure; this should be evaluated against specific application conditions.

The 1814634 provides superior current capacity (5A vs. 4A) and broader wire gauge acceptance (20-26 AWG vs. 22-24 AWG), both favorable characteristics for substitution.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1814634 directly replace the BL300-02-A in all applications?

A: Direct replacement is possible only if the application operates at or below 150V. The BL300-02-A is rated 300V; the 1814634 is rated 150V. Voltage requirement verification is mandatory before substitution.

Q: What does the 0.004" pitch difference (2.40mm vs. 2.50mm) mean for compatibility?

A: The pitch difference represents the spacing between connector positions. A 0.004" variance is within standard manufacturing tolerance for this connector class and does not prevent mechanical mating or electrical function. PCB layout may require minor adjustment depending on design margins.

Q: Are the housing materials interchangeable?

A: Both materials are thermoplastic polymers suitable for surface mount connectors. LCP (Liquid Crystal Polymer) offers superior thermal stability and dimensional consistency. Polyamide (PA/Nylon) is more cost-effective and widely available. Material selection depends on operating temperature, chemical exposure, and mechanical stress requirements of the specific application.

Q: Does the 1814634 support the same wire gauges as the BL300-02-A?

A: The BL300-02-A accepts 22-24 AWG wire. The 1814634 accepts 20-26 AWG wire, which includes the original range and extends it. Both gauges within the 22-24 AWG range are fully compatible with the 1814634.

Q: What is the significance of the packaging difference (tape & reel for the 1814634)?

A: Tape & reel packaging is standard for high-volume surface mount assembly. This packaging format is compatible with automated pick-and-place equipment and does not affect electrical or mechanical performance. It may reduce per-unit cost for production quantities.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BL300-02-A and 1814634 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
