Key Parameters

Substitute Part Grouping Explanation

Substitution of the WP7113PBC/A is determined by strict alignment of the following critical parameters:

Physical and Mechanical Compatibility:

• Lens size must remain 5mm T-1 3/4 package
• Mounting type must be through-hole radial configuration
• Lens style must be round with domed top
• Overall dimensions (5.00mm diameter, 8.60mm maximum height) must match

Optical Specifications:

• Color classification must be blue
• Lens transparency must be clear (colorless)
• Viewing angle must be 16°
• Wavelength dominant range must fall within blue spectrum (460-470nm acceptable)

Electrical Parameters:

• Forward voltage (Vf) tolerance: 3.2V to 3.3V acceptable
• Test current: 20mA standard reference
• Brightness (millicandela) may vary within active product specifications

Regulatory and Compliance:

• RoHS3 compliance required
• REACH unaffected status required
• Moisture sensitivity level MSL 1 (unlimited) required

The WP7113QBC/D meets all substitution criteria as an active product alternative.

Engineering Selection Recommendations

Primary Recommendation: WP7113QBC/D

The WP7113QBC/D is the direct active equivalent for the obsolete WP7113PBC/A. Selection of this substitute is based on the following engineering factors:

Product Status Alignment: The WP7113QBC/D maintains active product status with 33,906 pieces in current inventory, ensuring long-term availability and supply chain continuity compared to the obsolete WP7113PBC/A.

Regulatory Compliance: Both components maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, satisfying all environmental and regulatory requirements without design modification.

Physical and Mechanical Compatibility: Identical package specifications (5mm T-1 3/4 through-hole radial) ensure direct PCB layout compatibility without requiring board redesign or mechanical rework.

Electrical Compatibility: Forward voltage variance of 0.1V (3.2V to 3.3V) falls within acceptable circuit design tolerance for standard LED current-limiting resistor configurations. Test current remains constant at 20mA.

Optical Specifications: Wavelength dominant shift from 470nm to 465nm remains within blue spectrum classification. Both components maintain identical 16° viewing angle and clear lens transparency. The WP7113QBC/D provides enhanced brightness at 2700mcd compared to 1600mcd, offering improved visibility performance without optical characteristic degradation.

Base Product Number Continuity: Both components share the WP7113 base product number, confirming manufacturer-validated substitution relationship.

Frequently Asked Questions (FAQ)

Q: Can the WP7113QBC/D be used as a direct replacement for WP7113PBC/A without circuit modification?

A: Yes. The WP7113QBC/D is electrically and mechanically compatible. The 0.1V forward voltage difference (3.2V to 3.3V) is within standard LED circuit design tolerance and does not require resistor recalculation for typical 20mA applications. Physical dimensions and mounting configuration are identical.

Q: What is the significance of the wavelength shift from 470nm to 465nm?

A: Both wavelengths fall within the blue spectrum classification. The 5nm shift is imperceptible to human vision and maintains color consistency for indication applications. Both components are specified as blue LEDs with clear lenses.

Q: Why does the WP7113QBC/D have higher brightness (2700mcd vs 1600mcd)?

A: The increased millicandela rating represents enhanced light output performance in the active product generation. This provides improved visibility without introducing compatibility issues. Applications requiring the original brightness level can implement optical filtering or reduced drive current if necessary.

Q: Are there any packaging differences between the two parts?

A: The WP7113PBC/A is supplied in standard packaging, while WP7113QBC/D is supplied in bulk packaging. Both use identical component specifications and through-hole radial package configuration. Bulk packaging affects procurement quantity and logistics only, not component performance or compatibility.

Q: What compliance certifications apply to both components?

A: Both WP7113PBC/A and WP7113QBC/D maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. No additional compliance considerations are introduced by substitution.

Q: Is the 16° viewing angle maintained in the substitute part?

A: Yes. Both components specify identical 16° viewing angle with round domed-top lens style, ensuring consistent directional light emission characteristics.

Q: What inventory status should influence procurement decisions?

A: The WP7113PBC/A is obsolete with 855 pieces in stock. The WP7113QBC/D is active with 33,906 pieces in inventory, providing superior long-term supply security and supporting continued production requirements.
